One bubble, two bubbles, three bubbles, four... the physics of bubbles and how to eavesdrop on a breaking wave

Abstract
Breaking waves in the open ocean generate huge number of bubbles, and these bubbles have a significant influence on optics, acoustics, gas transfer and aerosol production in the upper ocean. However, measuring the bubble population is challenging because the large bubbles fragment or escape to the atmosphere rapidly and the smallest ones are invisible to most optical and acoustical techniques. I will discuss high-speed photography experiments which demonstrate how bubble dynamics is linked to the sound that bubbles produce naturally, and how these experiments will improve our ability to understand the upper ocean.
